Wouldn't it just! I don't really have access to any of these scopes. My only experience with Kowa was some years back, with an 80-82mm Kowa (don't recall the model) with the 27x LER eyepiece. I was overwhelmed by the eye relief and the bright image. Brilliant! But I was spotting a CF metallic silhouette match, where you either hit the target or miss it. No chance to evaluate resolution at long range. One thing that really got my attention besides eye relief, though, was that it was the first time I could actually see the bullets in flight. I hadn't yet tried bench rest, and the only time before this that I could see projectiles in flight was 105mm howitzer rounds firing high angle. Since then I've learned that seeing bullets in flight is no great trick, at least with .22LR looking thru a decent scope of 24x or more. Not much luck seeing .223's in flight, even with a good 36x.
I appreciate your input more than you know. I've vacillated all over the place over (1) which scope to buy, and (2) whether to even make the upgrade at all. For benchrest, at least at my club level, eye relief is not really that important. Our matches are not timed, so there's plenty of time to look thru the spotting scope. What matters most, I think, is magnification and resolution. Mostly the latter. My Konus works just fine at less than 200 yds on a bright day without too much mirage. And it's great for spotting .22 holes in the white on almost any day; again, at 200 yds or less. It starts getting tricky on overcast days, with .22's in the black. Sometimes I think I'm doing just fine, then get a nasty surprise or two when I retrieve my target.
So given these considerations, I think I'm going to go with the 65mm Celestron Regal. The Vortex Viper HD is another contender, but from most of the reviews I see that these 2 scopes are on pretty much a par, optically, and the Celestron is $200 cheaper.
I do appreciate the info. Thanks again! For that matter, many thanks to all who replied.
